BALING- lPATENT* OEEICE.

LYNCHBURG, VIRGINIA.

PRESS.

SPECIFICATION forming part of Letters Patent No. 701,575, eared :rune 3,1902.

Application filed August 24|v T0 all whom it may concerns v Be it knownthat I, MICHAEL KIRSHNER, a citizen of the'United States of America, anda resident of Lynchburg, in the county of Campbell and State ofVirginia,have invented certain new anduseful Improvements inBaling-Presses,of which the following is a specication. A v I Thisinvention relates toimprovements in the art of compressing and balingcotton and other material, andv has for one of its objects a machine orpress which can Agive the complete compression to the material in asingle machine instead of in two machines, as is generally the presentpractice. It is now quite the usualpractice to give preliminary pressureto the cotton at the plantation, and then the partly-pressed bale has tobe removed to a more powerful press, sometimes at a great distance,where the final compression is given.

It is my aim to provide a press that is so simple and withal soefficient and powerful that it can be made sufliciently cheap to bewithin the reach of all plantations, sothat` the complete compressioncan be given to the material in a single press before the bale isvshipped. i

Another object is to provide a machine that will be suitable for baling,the material in a practical and commercial fire and Ywater proofcovering. p j v,

With these andother objects in view,which will be hereinafter set forth,my invention consists in a press of the peculiarconstrnc'- tion,arrangement, and combination of parts, as hereinafter described initspreferable embodiment and then definitely set forth by In thedrawings which accompany and illus-V trate one way of carrying out myinvention, Figure 1 is a side elevation of a press made in accordancewith my invention, but with parts broken away to better show theoperating mechanism. Fig. 2 is a vertical central section of the same.Fig. 3 is a horizontal section throughthe.cr ib s.. Fig. 4 is a group ofperspective views, showing the'two cribs and the movable bed-plate. Fig.5 isa sectional detail through the bale. Fig. G is a perspective View ofa knockdown frame. Fig.

7 is a perspective detail of the movable bedserin no. 73,183. (No model)are securely bolted the upper cross-heads 3 and 4, within which issecured the -upper or stationary crib 5. This stationary crib is formedof a frame consisting of four cornerposts 6,which are connected togetherby crosspieces 7 on th'esides and wedge-shaped crossi pieces 8 on -theends, which'latter'rest on the cross-heads 4, as shown in dotted linesin Fig. land in'full lines inFig."5.j AThe said crib 5 also consists ofa series' of Vertical lslats9 between the c'orner-postsnas' clearly seenin Fig. 4.' l c' 'i M Coacting with the aforesaid stationary crib 5 isalslidingcrib' 10, consisting ofga rectangnlarframellandaseries ofupright or vertical slats 12, which' are so spaced that they llitbetween the slats 9 of the stationary crib 5.v and slide or `telescopetherein, as clearly shown in jFLig. '1. vThis sliding crib is lined withsheet metal or any other suitable material 13, and this lining 13 isprovided with two slots or openings 14 for a purpose to be `hereinafterdescribed.

15 designates a plunger or.. follower which is adapted to enter thecribs 5 and 10 and give the preliminary pressure to the material to bebaled, and this plunger 15 is pivotally connected to a pair of curvedconnecting-rods 16 "16,'which in turn are pivotally connected to a pairof blocks v1,7 A17, fixed toa pair of swinging arms 18 18, pivotedtlovthe main or fixed A,bed-plate 1. 't Pulleys 19 19 are journaled withinthe blocks 17 '17, and a rope v2O passes from these pulleys toa drum 21,mounted on and revolving with the shaft 22, driven from any suitablesource of power. 'Itwill be obvious froin'the foregoing and theaccompanying drawings that when power isfa'pplied to the shaft 22 towind the rope 2O on the drum 21 the ends of the swinging arms 18 18 arebrought toward each other, which causes the plunger or follower 15 torapidly enter IOO in the positions shown in Fig. 2, and two heavy metalbars 23 23 are then passed under the cross-heads through the openings inthe cribs and the openings or slots 14 in the criblining 13, when theplungeror follower 15 becomes fixed and now serves as a fixed platen,

against which the material is given its finalY compression, ashereinafter described.

Mounted on the posts or standards 2 is a sliding compressing-follower,that I shall hereinafter term the movable bed-plate 25, which is capable'of a vertical sliding movement on the said posts or standards and whichhas formed on or connected therewith extended bosses 26, which providelong bearings on said posts and give great steadiness and rigidity totheir movable bed-plate. This bed-plate is also provided with a pair ofdepending ribs or cross-bars 27, from which project two pairs of hubs2S, forming a bearing for part of the mechanism for giving the finalcompression to the cotton or other material being operated upon. Boltedor otherwise secured to the fixed bed-plate 1 is a somewhat similararrangement consisting of a central web 30 and two pairs of hubs 31.Each pair of these hubs 2S and 31 (there being four pairs in all)support journals or axle-pins 32 32 and 33 33, the journals 32 3o beingsituated directly over those numbered 33 33, and on these journals arerotatably secured the eccentric rollers or cams 34 34 and 35 35. Theseeccentric rollers or cams are also arranged in vertically-disposedpairs, the rollers or cams 34 being in rolling contact with the rollersor cams 35. As these eccentric rollers or cams revolve or roll on eachother they necessarily cause their journals or axlepins to separate ormove one away from the other, and as the lower set is fixed it followsthat the whole movement is imparted to the upper set of journals, and asthe latter support the movable bed-plate 25 the said bed-plate isthereby given vertical movement.

To impart rotary movement to these eccen-A trically-set rollers or cams,I form recessed gears 36 36 and 37 37 in said rollers, and between eachpair of these gears (which in reality are worin-wheels) mesh worms 39and 40, which are formed on opposite ends of a shaft 41, on which isfixed a worm-wheel 42, gearing with a worm 43, driven from a shaft 44 byany suitable power. (Not shown.) As the eccentric rollers 34 35 roll oneach other and their journals approach or move away from each other, itis necessary to provide some means of supporting the shafts 41 and 44,the worin-wheel 42, and the worm 43, so that these parts may movevertically in order to accommodate themselves to the vertical movementof the eccentric rollers. To permit this movement, I employ the bearing46 for the shaft 44, which bearing .is forked or bifurcated at 47 tosupport the shaft 41, the said bearing 46 having guides or standards 48,which pass through openings 49 in the fixed bed-plate l, and therebyretain the bearing 46 in its proper position.

On the movable bed-plate 25 are formed or secured bars 50, providing arecess 51, specially adapted to receive or hold a pan 52, which formsthe bottom or lower part of my improved bale-coverin g claim ed in aseparate application filed August 24, 1901, Serial No. 73,184. A similarpan 53 forms a top or upper part of my bale-covering, and I provide aknockdown frame formed of two parts 55 and 56, which is arranged tocoact with said pans when the bale is being compressed. This frame isshown in perspective detail in Fig. 6 and is of the proper size to reston the bars50,hereinbel`ore mentioned. Thisknockdown frame is formedwith an inwardlyswelled or convex portion 57, the use and purpose ofwhich will be hereinafter described, and with openings or slots 58 topermit the air to escape as the material is compressed.

The above is a description of the preferable embodiment of my press, andits operation is as follows: Assuming that the movable bedplate 25 andits operating mechanism are in the positions shown in Fig. 1, themovable crib 10 is pushed upward, the lower or bottom pan or section ofthe bale-covering 52 is placed within the recess l, and the frame 55 56is placed over said pan and on the bars 50, and the aforesaid movablecrib is then moved downward until it rests on the frame 55 56, asclearly shown in Fig. 1. The cotton or other material to be formed intothe bale is then fed into the upper crib, and when a sulicient quantityis placed therein it is given a preliminary pressu re by applying highor rapid power to the shaft 22 and drum 21, thereby winding the rope 2Oon said drum, drawing the swinging arms 13 18 toward each other, andforcing the plunger or follower within the crib 5 and giving the initialor preliminary pressure to the bale. Owing to the fact that the cottonor other material has not had any pressure before this action, a rapidmovement can be given to the follower or plunger 15, and when the latterreaches the point shown in Figs. .2, 3, and 5 the heavy cross-bars 23are inserted under the crossheads through the slots in the cribs. Thesecross-bars 23, coacting with the cross-heads'3, will prevent the plungeror follower 15 from moving upward, andthe latter now serves the purposeof a fixed platen, against which the final compression is made. Power isnow applied to the shaft 44, which slowly operates the worms 39 and 40through the medium of the worm 43 and worm-wheel 42 and rotates theeccentric rollers or cams, and as the latter roll on each other theupper shafts or journals 32 32 are caused to slowly ascend, which ofcourse moves the movable platen IOO IIO

upward and gives the final compression to the material between'the twopans 52 and 53. It will be evident from an inspection of my drawingsthat owing to the gearing the upward movement is made very slowly andthat as the rollers orl cams are eccentrically set with relation totheir axes the leverage increases as the upward movement is continued. vI deem this very important,vas by its use Isecure a most powerfulmechanism with very little wear and tear and an imperceptible amount offriction. When the rollers move just'half-way around, then the axes areat their extreme positions, and the bale is now compressed and power isshutoff and the rmovement of the movable bed-plate stopped.

I here wish to call particular attention to the shape of the interior ofthe knockdown frame o 56, which is formed with an inward swell or convexportion 57, which as the material is pressed causes a correspondingconcavesurface between the pans, as seen in Fig. 2, so `that it will notbe dificult to secure a fastening device to the pans. Some method offastening the pans 52 and 53 must now be performed, and this isaccomplished by first pushing the sliding crib slightly upward andthenremovingthe knockdown frame 55 56, which maybe done by removing thetwo screws securing the parts together. A fastening-strip 60,providedwith hooked flanges 6l and 62, is then bent'around the bale, so that thehooked lianges 61 and 62 are in theproper position to coactwithsimilarly-hooked flanges 52t and 53',on the pans 52 and 5,3. In order tocause the hooked anges to properly engage eachbther, I prefer to firstWedge or force a bar 63 between the rear side of the fasteningstrip60'and the posts 2 2, then force end bars 64 and 65 between the ends ofsaid strip 460 and said posts 2 2, and finally forco a pair of thin bars66' and 67 on the front, all as clearly seen in Fig. 7, `in which` thobale is shown in dotted lines. As the bars 66 and 67 have a space leftbetween them,

a suitable tool can-be inserted to bend down.

the tongue 68, which must previously have been inserted through thevslot 69. The fastening-strip is now held closely against the pans 52 and53; but the hooked flanges are not in engagement with each other. Tomake them engage each other, the-operator applies power to the shaft 44,which through the intei-mediate gearing causes the movable bedplate 25to descend, and the expansivev forcev of the cotton causes the pans toseparate sufficiently to engage the hooked flanges of the locking-stripwith the hooked a'nges of the pans 52 and 53, when said pans will besecurely locked together. The bars 63, 64, 65, and 66 may now beremoved, and after'the movable bed-plate has been allowed to descend thecovered bale may be removed from t the press ready in every respect forshipment.-

. From the foregoing it will be seen that I have invented and produced asimple press for baling cotton and other material which is so simple andyet so very efficient that it can be used on the plantation to entirelycompress l the bale in a single machine instead of two, as are nowgenerally employed. It'will also be seen that when the material is baledit is in a fire and water proof covering that not only makes shippingand storing much safer, but materially reduces the care necessary in itshandling, as well as the insurance rates, which arehigh for the oldstyle of coverings.

I have shown in my drawings what I consider one of the embodiments of myinvention; butit will be manifest to all that I do not limit myself tothe exact constructions and combinations shown, as various alterationsor modifications may be made at -will or Y one part or set of parts usedwithout other parts without in any way departingfrom the line of myinvention. Merely as examples it may be mentioned that thebars 50 may bemade integral with the bed-plate 25 or they may be formed separately andsecured theron, and the teeth forming the worm-Wheels 36 36 and 37 37may be made integral with the eccentric rollers or they can be securedthereto, so as to rotate therewith'. Hence where in my claimsy I havespecified the eccentric rollers as having gears or worm-wheels formedthereon I mean to cover the eccentric rollers made with teeth in any wayequivalent to that Shown.
